The shooting came just hours before a vigil was planned at the site by the Mothers Against Gun Violence.

The woman's name has not yet been released; police are still trying to contact her family, Sgt. Thomas Connellan said.

A man, wearing a white T-shirt and covering his face, came from a backyard and onto a driveway between two houses, at 105 and 107 Knaul St., around 3:20 p.m., Connellan said. The man, armed with a gun, approached the woman "and shot her at point-blank range," Connellan said. "He got very close to her and shot her at least once."

Moments after the shooting, James Nazarkiewicz called the woman's cell phone. He had let her borrow his van, and she hadn't showed up to return it. Someone answered her phone and Nazarkiewicz said he listened to people scream.

Nazarkiewicz said he let the woman, a friend of his wife, borrow his blue Kia minivan around 10 p.m. Saturday so she could go to a movie and then visit the memorial site for her friend, Karon Cole, who was shot and killed July 16 in front of 107 Knaul St.

"I talked to her about (Cole's murder)," said Nazarkiewicz, of Syracuse. "I know she was pretty upset about it."

Nazarkiewicz said the woman was friends with Cole and she wanted to attend a vigil for him Sunday.

Mothers Against Gun Violence vigil planned for Sunday evening in the 100 block of Knaul Street, where the 22-year-old father of two was gunned down, was called off, as police cordoned off the street near Schiller Park to investigate the second shooting in less than a week.

The woman was taken to Upstate University Hospital, where she underwent surgery shortly after the shooting, Connellan said. She later died.
